要获得Android密钥哈希码，请遵循以下步骤:

下载OpenSSL for Windows 现在解压缩到C盘 打开CMD提示符 输入cd C:\Program Files\Java\ jdk1.6.0_26\bin 然后只输入keytool -export -alias myAlias -keystore c:\ users \您的用户名\。android\myKeyStore | C:\openssl-0.9.8 k_win32 \bin\openssl sha1 -二进制| C:\openssl-0.9.8 k_win32 \bin\openssl enc -a -e 完成

这是Facebook官方页面上给出的内容:

   keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

让我把这个命令分解成几个片段。

Look for "keytool.exe". You can search that on the C: drive. You can find it in "java jdk" or "java jre". If you have installed multiple versions, choose any. Open a CMD prompt and go to the above directory where you found "keytool.exe". Clip the "exe`" and paste the above command provided on the Facebook page. You will get an error on entering this that OpenSSL is not recognized as in input output command. Solution : Download "Openssl" from OpenSSL (if you have a 64-bit machine you must download openssl-0.9.8e X64). Extract and save it anywhere... I saved it on the C: drive in the OpenSSl folder Replace the openssl in the above command in which you was getting an error of OpenSSL with "C:\OpenSSL\bin\openssl" at both the places after the pipe, "|". If prompted for a password, enter android.

你会得到你的哈希键。要了解进一步的步骤，请再次参考Facebook页面。

这个方法对我来说很有效，我做了一些观察:

每个SHA1密钥都有一个对应的密钥散列，长度为28个字符，以'='结尾 我尝试过在线工具来获取我的SHA1的哈希键，但这个哈希键从来没有为我工作过。 如果你在windows上安装Open -ssl:Open ssl 我已经在我拥有的所有密钥存储库文件上使用了这个keytool命令，即登台、调试和发布。

keytool -exportcert -alias my_alias_name -keystore "C:\Users\...my_filename.jks" | "C:\Openssl\bin\openssl.exe" sha1 -binary | "C:\Openssl\bin\openssl.exe" base64

注意: 上面的方法总是会给你一个键散列，即使你填错了任何参数。知道你是否得到正确的散列键的技巧是——运行这个命令后，如果提示输入密码，这意味着后续的键是正确的。

不要使用my_filename。密钥存储库，但使用my_filename代替。jks。

以下是步骤

Download openssl from Google code (If you have a 64 bit machine you must download openssl-0.9.8e X64 not the latest version) Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here. detect debug.keystore file path. If u didn't find, then do a search in C:/ and use the Path in the command in next step. detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line- $ keytool -exportcert -alias androiddebugkey -keystore "C:\Documents and Settings\Administrator.android\debug.keystore" | "C:\OpenSSL\bin\openssl" sha1 -binary |"C:\OpenSSL\bin\openssl" base64 it will ask for password, put android that's all. u will get a key-hash

下载openSSL for windows，你可以在这里找到64位和32位的 解压缩下载的文件 在C盘中创建文件夹名为openSSL 将所有提取的项目复制到openSSL文件夹(bin,include,lib, openSSL .cnf) 获取android调试密钥库，默认位置为

C:\Users\username\.android\ debug.keystore

现在获得命令提示符并粘贴这段代码

keytool -exportcert -alias androiddebugkey -keystore C：\Users\username.android\debug.keystore |“C：\openSSL\bin\openssl” sha1 -binary |“C：\openSSL\bin\openssl” base64

按enter键，你会得到28位的键码

Simply Open you Main Activity File and create below mention function: try { PackageInfo info = getPackageManager().getPackageInfo( "your.application.package.name", PackageManager.GET_SIGNATURES); for (Signature signature : info.signatures) { MessageDigest md = MessageDigest.getInstance("SHA"); md.update(signature.toByteArray()); Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT)); } } catch (PackageManager.NameNotFoundException e) { } catch (NoSuchAlgorithmException e) { }

1.1运行你的应用程序，这将为你的应用程序生成一个哈希键。

现在，打开日志猫和搜索“KeyHash”和复制哈希键。 一旦你生成了哈希键，你可以删除这个函数。
